Trying to connect to Linksys Route to laptop

Hello,

I purchased a 2nd laptop and am trying to add it to the Linksys router with no success. I also forgot the password. I have typed 192.168.1.1./ and put admin in the user column first, which gives me an error message 401. I typed "admin" in the password column and it has been trying to pull up the security window but only goes 1/3 across the bar. I really need some help.
